Q1) Rohit rides to his school from his home at a uniform speed. While returning, he covers two-sevenths of the total distance at two-sevenths of the speed maintained during the onward journey. Then he increases his speed by 50% and covers three-fifths of the remaining distance at this speed. He finally reduces his speed by 66.67% and maintains this speed till he reaches his home. If his average speed for the to-and-fro journey is 14km/h, find the speed (in km/h) at which Rohit rides to the school.
Q2) A faulty clock gains 10 minutes every hour. If the time is set correctly at 12 Noon on 1st Jan 2010, then how many times will its minute-hand and hour-hand meet in the next 24 hours ?
Q3) Three boys A, B and C start running at constant speeds from the same point P along the circumference of a circular track. The speeds of A, B and C are in the ratio 5:1:1. A and B run clockwise while C runs in the anticlockwise direction. Each time A meets B or C on the track he gives them a card. What is the difference in the number of cards received by B and C if A distributes 33 cards in all?
Q4) A bike running at 80 km/h initially is slowed down to 60 km/h as soon as the fuel indicator touches the half level mark. It keeps running at this speed till it runs out of fuel, thereby covering a total distance of 640 km in 10 hours. If the bike consumes 2 litres of fuel per hour, what is the capacity (in litres) of the fuel tank of the bike?
Q5) P and Q are two points on a river, and the direction of current is from P to Q. A motorboat goes from P to Q in 4 hours and comes back to P in 6 hours.

a. 3 hours
b. 3.5 hours
c. 2.5 hours

Q6) A goods train and a passenger train are running on parallel tracks in the same direction. The driver of the goods train observes that the passenger train coming from behind overtakes and crosses his train completely in 60 s, whereas a passenger on the passenger train observes that he crosses the goods train in 40 s. If the speeds of the goods train and passanger train are in the ratio 1 : 2, then the ratio of the lengths of the goods train and that of the passenger train is
a. 1 : 3
b. 2 : 3
c. 4 : 3
d. 2 : 1
Q7) Lucknow Mail, which runs between Lucknow and Delhi, leaves Lucknow at 8.30 a.m. and travels at 80 km/hr towards Mathura situated 300 km away from Lucknow. Satabdi Express, runs between Lucknow and Delhi, leaves Lucknow at 9.00 a.m. and travels at 100 km/hr. Just when Satabdi crosses Lucknow Mail, Prayagraj Express travelling at 50 km/hr leaves Mathura towards Lucknow. When will Prayagraj Express meet Satabdi Express?
a. 11.50 a.m.
b. 11.40 a.m.
c. 11.00 a.m.
Q8) Mr. Perumal decided to walk down the escalator of a tube station. He found that if he walks 26 steps, he requires 30 s to reach the bottom. However, if he walks 34 steps he would only require 18 s to reach to the bottom. If the escalator is moving downwards, find the number of steps in the escalator.
Q9) Vijay went from A to B at a certain speed and came back to A from B at a speed that was 12 times the speed at which he went from A to B. The entire journey took 9 hr. Had Vijay come back at a speed that was only half the speed at which he actually returned, how long would it have taken him for the entire journey?
Q10) A junction of two highways is patrolled by two cars, one on each road. Each car covers a distance of 5 km on either side of the junction on its road. If the speeds of the 2 cars are 50 km/hr and 75 km/hr and they start from the junction at 6 a.m. from the same point, when will they meet next time?
a. 6 : 16 a.m.
b. 6 : 24 a.m.
c. 6 : 30 a.m.
d. 6 : 48 a.m.
Q11) A swimmer started swimming from Baghbazar Ghat towards Ahiritola Ghat against the stream. At Ahiritola Ghat he saw a floating log. He continued swimming, in the same direction as before,till Howrah Ghat and after reaching there, he immediately turned and started swimming back. Coincidentally the log and the swimmer both reached Baghbazar Ghat at the same time. If Howrah Ghat is 20 km away from the Ahiritola Ghat and the swimmer took thrice the time for ongoing journey that he took while coming back, then what is the distance between Baghbazar Ghat and Ahiritola Ghat?
a. 60 km
b. 20 km
c. 10 km
d. 40 km
Q12) Two friends – Prakash and Arpit – started running simultaneously from a point P in the same direction along a straight running track. The ratio of the speeds of Prakash and Arpit was 2 : 5 respectively. Two hours later, Arpit turned back and started running backwards at one-fifth of his original speed. He met Prakash at a distance of 10 km from the point P. What was Prakash’s running speed?

Gia takes 6 more min to reach the top from the bottom of the escalator if he goes up on the escalator moving downward as compared to when he does so on the stationary escalator. They start simultaneously from the top and the bottom of the escalator, moving downward, respectively and meet after 4 minutes. How many steps are there in the escalator?
